While most keyboards are identical to one another, some employ special features such as multimedia keys, power buttons, palm rests, and more. Depending on the type of keyboard, certain features may be present or omitted.
Types of Keyboards
There are multiply keyboard categories that function according to a specific purpose. One common keyboard type is a mechanical keyboard that features keycaps with mechanical switches underneath. You can quickly identify this type as it produces a resounding click sound when you push a key. This type is commonly found with desktop computers since it occupies more space and utilizes an expensive design. There’s also the chiclet-style, which is the most common type of keyboard found on laptop computers. The keys are flat, elevated, and don’t slope off around the edges to create an impression of gaps between the keys. Cleaning is much easier with a chiclet-styled keyboard compared to the mechanical type. On the other hand, the traditional type employs keys that are placed firmly into one another with each key edge sloping off. The space between keys measures about a millimeter, and it can be entirely removed from the device to be replaced by a single piece. Your laptop keyboard keys perform a lot more than just type letters and numbers. They also deliver several functions that make any task faster and more comfortable. A laptop keyboard also possesses a different layout compared to the desktop keyboard. Hence, familiarizing yourself with its unique features and functions allows you to determine and diagnose the problem if your keyboard is not working correctly.
